Description
Pole-skipping is a phenomenon when lines of poles and zeroes of retarded Green's function intersect- which means a would-be pole gets skipped in a complex $\omega-k$ plane. People have claimed these points are connected to the Lyapunov exponent and butterfly velocity of a chaotic system. In this talk, I will show the effect of scalar-Gauss-Bonnet coupling (higher curvature term coupled to the scalar field) on these Pole-skipping points in shear and sound mode analysis. The connection to chaos will also be discussed.
